English - Lockdown is a semi-cooperative game that takes you into a horrific world overwhelmed by Monsters which you know nothing about … besides their veracious appetite for your skinny little human bodies. Semi-cooperative means that you win alone, but you will have to help others to get there. You will create temporary alliances, you will lie, betray for the sole purpose of making sure that your family survives.
